Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.

Atropa belladonna is a valuable medicinal plant and a commercial source of tropane alkaloids, which are frequently utilized in therapeutic practice. In this study, bioinformatic methodologies were used to examine the pattern of coding sequences and the factors that might influence codon usage bias in the chloroplast genome of Atropa belladonna and other nightshade genomes. The chloroplast engineering being a promising field in modern biotechnology, the characterization of chloroplast genome is very important. The results revealed that the chloroplast genomes of Nicotiana tabacum, Solanum lycopersicum, Capsicum frutescens, Datura stramonium, Lyciumbarbarum, Solanum melongena, and Solanum tuberosum exhibited comparable codon usage patterns. In these chloroplast genomes, we observed a weak codon usage bias. According to the correspondence analysis, the genesis of the codon use bias in these chloroplast genes might be explained by natural selection, directed mutational pressure, and other factors. GC12 and GC3S were shown to have no meaningful relationship. Further research revealed that natural selection primarily shaped the codon usage in A. belladonna and other nightshade genomes for translational efficiency. The sequencing properties of these chloroplast genomes were also investigated by investing the occurrences of palindromes and inverted repeats, which would be useful for future research on medicinal plants.

We investigated traditional knowledge about ethnobotanical uses around national parks in the northern areas of Province Gyeongsangbuk-do, with the focus on the Sobeaksan National Park area. Interviews were carried out to 138 residents at 42 places from 7 counties and/or cities, and verified species and usage information were categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 277 taxa: 244 species, 3 subspecies, 28 varieties, and 2 forma in 213 genera of 79 families. The significant native plants included one Endangered Species (Paeonia obovata Max.) and four endemic species (Salix hallaisanensis H. Lev., Aconitum pseudolaeve Nakai, Paulownia coreana Uyeki, and Cirsium setidens (Dunn) Nakai, Sasa coreana Nakai). About 17 Approved Species for Delivering Overseas designated by Korea Ministry of Environment have been also traditionally valuable in the regions. The main usage of the plants were edible (185 taxa) and medicinal (175 taxa). Leaves were most commonly used parts (109 taxa), followed by stems (73 taxa), fruits (69 taxa), roots (67 taxa), and wholes (57 taxa). The traditional usage of plants were diverse as those useful parts. Leaves, fruits and seeds were used as edible and medicinal; sprouts (young shoots) were mainly used as edible; but roots and flowers were used as medicinal. The study does not only provides examples of traditional uses of native plants, but also facilitates sustainable managements and developments of ethnobotanical knowledge for the contemporary society.

Background and objective: The purpose of this study was to comprehensively analyze the user behavior in order to cope appropriately with the increasing demand for mountain usage of those in their 20s and 30s and to allocate resources efficiently. Methods: To analyze the behavior of mountain hiking users, an exploratory data analysis (EDA) was conducted on the data which had been collected in the app Tranggle. The main target are users in their 20s and 30s who visited the mountains in the metropolitan area in 2019-2020. Among them, we have selected data on the top 13 mountains based on the frequency of visits. After data pre-processing, mountain usage patterns were analyzed through statistical analysis and visualization. Results: Compared to 2019, the number of users in 2020 increased 1.36 times. The utilization rate of the well-established hiking trails has also increased. The usage of mountain on weekends (Saturday > Sunday) was still the highest, and the difference in the usage between the days of the week decreased. Outside of work hours, early morning usage has increased and night-time usage has decreased. There was no significant change in usages depending on activity type, level (experience point) and exercise properties. Conclusion: Since the COVID-19 outbreak, the usage of mountains has been changing towards low user density and short-distance trip. in the post-COVID-19 era, the function and role of forests in daily life are expected to increase. To cope with this, further research needs to be carried out with consideration of the wider demographic and social characteristics.

Demand of LPG and LNG will increase continuously due to high calories, clearness, and convenience for usage. These gases are used widely for power plants, industrial plants, and domestic fuel. But accidents related with gas are increasing in proportion to increment of gas usage. Especially LPG has high ignitability due to weak dispersion to air and accumulation at low place because LPG is heavier than air. There are many hazards during transportation as well as production, storage, and usage of LPG. Commonly, tank lorry is used for inland transportation of LPG. If tank lorry were to raise leakage incidents and then LPG released during transporting, the accidents cause serious effects on the environment as well as human damage of surrounding area. In this study, therefore, hazards which cause LPG of tank lorry to leak during transportation were identified and risk of LPG transportation was assessed quantitatively. Also, the result of this study might be a useful measure for predicting damage and preparing safe transportation strategies of LPG tank lorry.

Many patients with psoriasis look for treatment options other than conventional treatment to control their disease with less side effects. We evaluated the prevalence and characteristics of herbal therapy usage among patients with psoriasis in Turkey. A self-prepared questionnaire about herbal therapies was applied to the psoriatic patients attended our dermatology clinic between October 2013 and December 2013. A total of 100 patients (55 male, 45 female; 7 - 80 years of age) were included in this study. Fortynine percent of patients used at least one form of herbal therapies. Juniperus oxycedrus and Aloe vera were found to be the most frequently used plants. 36.7% of the patients get benefit from herbal therapy. Only 12.2% of patients had informed their clinicians during or after herbal therapy usage. 22.4% of the patient had continued conventional treatment during herbal therapies. Side effects related with herbal therapy were developed in 26.5% of the patients. The risk of side effects was found to be 5.23 times more in patients using phytotherapies systemically compared with ones using topically. Our results show that herbal therapy usage is common among patients with psoriasis in Turkey. Since herbal therapies have the potential of interacting with the medical treatment modalities and causing life threatening allergic reactions, clinicians should be aware of plants used in psoriasis and possible adverse reactions related with them and also should not forget asking about herbal therapy history.
